Zircon Rapid Setting Compound
Vitcas® Zircon Rapid - High-Performance Zircon-Based Repair Compound
Vitcas® ZR - Zircon Rapid is a two-part, zirconium silicate-based repair compound developed for critical, high-temperature applications requiring rapid setting, exceptional refractory properties, and dimensional stability. Supplied as a high-purity powder and liquid solution, the material can be mixed to a brushable paste, putty, or pourable consistency, depending on the application. Zircon Rapid begins setting in approximately 5 minutes, becoming rock-hard within 15 minutes (ambient temperature dependent). Once cured, it remains stable at temperatures up to 1750°C, making it ideal for demanding applications in the investment casting industry and element embedding processes.
Typical Applications:
Investment casting industry:
- Repair of cracks in ceramic shells
- Sealing wax outlet vents
- Targeted coating of critical shell areas to promote directional solidification and improve casting quality
Element bedding:
- Can be mixed and poured into moulds to embed heating elements
- Forms rapid-setting ceramic blocks that can be fired without degradation, retaining high mechanical integrity
Key Features:
- Zircon-based, non-cementitious formulation
- Two-part system: precision-milled powder and reactive liquid
- Fast setting - initial set in ~5 minutes, hard in 15 minutes
- Refractory up to 1750°C
- Strong adhesion and minimal shrinkage
- Suitable for brush, trowel, or pour application
- Ideal for high-precision shell repair, masking, and component encapsulation
